0n the inner end of the barrel portion 1s formed a hollow cylindrical brake drum 25coinprising a radially projectingIv circular plate having on its outer edge an annular flange 26 with which is adapted to be engaged any suitable construction of brake band '(not shown). The radial plate of the drum forms one side of a spoke receptacle, the other side of which is in the 'form of an annular spoke clamping plate 2T which is slidably mounted on the barrel portion 23 of the driving'ineinber 16 of the hub. The driving member when constructed as described, forins one unit of the hub and is the medium through which the movement of the driving axle is imparted to the wheel and through which all strain resulting. from the application. of'the brake band to the drum is transmitted directly 'tothe driving axle.

lhe spokes 28 of the wheel are clamped between the radiall plate of the drum and the clamping plate 2i by a. series of clamp-v ing bolts 29 arranged through said plates between the spokes7 said bolts having nuts 30 on their outer ends which engage the plate 27. By thus fastening the spokes Jthey may bc readily removed and replaced without distiu'bingthe other parts of the hub and by adjusting the clamping plate 27 spokes of different sizes may be secured to tha wheel.

ievolubly mounted on the stationary axle 2 at 'the inner end of the bearing of the hub is an annular retaining plate 3l having a central offset portion in the inner side oi which is an annular chamber or recess 33. Around the edge of the recess 33 is an annular notch 3a'- which engages an annular otset 35 on the inner end of the barrel portion of the hub. T he outer portion of the plate 3l nts closely against the outerside of the radialv plateol the drum and is sen curely fastened to said plate by the head ends of the spoke clan'iping bolts 29, said ends of lthe bolts being squared where they engagethe plate 3l, as shown. ln the inner axle engaging edge of the plate 3l is an annular recess 36 in which is arranged a packing ring 3i' which tits around and forms a dust tight engagement with the axle The end of the stationary axle 2 having the notches 13 is also exteriorly threaded and on said threaded end is screwed a hubretaining nut 38 which engages the locking washer 1l and holds the hub in place on the axle. rThe nut 38 has in its edge a groove Engaged with the groove is a locking spring ll hating one end bent at right angles to form a nut locking pin 42 which projects through the passage -lO and is adapted to engage one of the notches 13 whereby thc nut is held against casual unscrewing troni the axle.

fln the stationary axle 2 at the opposite l maigre end of the bearing sleeves Vand rollers is an end thrust bearing i3 which is designed vto take 'up the end thrust of the hub both inwardly and outwardly. The bearing 43 is arranged in the:.recess of the locking plate 3l and comprises an annular thrust receiving plate or ring which engages the inner ends of the roller bearing sleeves t3 and S and has on its outer side an annular groove 45 Awhich forms one side of a ball race, the opposite Side ot' which is formed by an annular groove 46 in an outer thrust plate or ring 47 arranged on the axle 2. lingaged with the grooves ll5 and 46 are a series of anti-friction thrust bearing balls 48 which are held in place by inner and outer rings illland 50 as shown. The outer thrust plate 47 has the outer corner of its inner edge beveled oif as shown at 5l to engage the shoulder 3 formed by the reduced endio the axle 2. By constructing .and arranging the thrust bearing 4:3 as herein shown and described, the inward thrust of the wheel will be received by the thrust receiving plate la at the point a in Fig. l, or .where the plate is engaged. by the .inner end of the outer bearing sleeve 8 of the roller bearing. The outer thrust of the wheel will be received by the plateat the point Z) in Fig. l, or where the plate 1s engaged'by the inner end of the inner bearing sleeve 6. The

inward thrust of the wheel is indicated in liig. l of the drawings by the arrow a: while the outer thrust bearing is indicated by the arrow y. It will thus be seen that the thrust bearing 43 serves to resist both the inner and outer thrusts o'f the wheel and dispenses with the necessity of providing a thrust bearing in both ends of the hub.

lnY the preceding description, I' have described the barrel of the hub as being provided with a. radial plate, which plate is integrally united with the brake drum 26, have set forth the fact that the retaining plate 3l contacts with the plate in question, that an vannular spoleclamping plate 27 slides upon said bar1el,that the spokes 28 are interposed between the radialplate and said plate 27', and that one series or bolts 29 passes through the plates on the two sides of the spokes, through the intervening spokes, and through said retaining plate. lt may, however, be well to here further eX- plain the advantages resulting from 'this construction.

ln so doing, it may be first explained that it often becomes necessary to remove the spokes and rim of the wheel, as a unit, from the hub thereof, in case part of the wheel or the tire thereof has become injured, thereby allowing the application oa new7 nWheel. which may well be carried by the vehicle equipped with the invention. In order to so remove the wheel,` it is simply necessary to nuts. on these 'bolts will allow disassembling remove th-u nuts from the bolts 29,l thus allowing the spoke clamping plate or ring 27 to be moved outwardly from the hub, after which' the spokes and the rim of the wheel may be removed as a unit.

Furthermore, it often becomes necessary to adjust and repair the lvariousbearings within' the barrel or hub. In 'order to'accompli'sh this result, it is again only necessary to remove. the nuts from vthe bolts'29, after which the 'entire wheel and the hub thereof may be removed from said bearings, thus allowing the properadjustments or repairs to be readily made. It will be understood .that the retaining'plate 31 remains upon the fixed axle section 2, at all times, although this plate may be movedinwardly thereon to vinspect or repairthe thrust bearing.

ln view 'of the preceding explanation, it will be evident that the specific structure set -forth in the following claim possesses a great number of advantages, regardless of its extreme simplicity. Particular emphasis is laid upon the fact that the one series of bolts 29 secures all ofthe movable parts of thehub together, and that removal of the in the manner above set forth, it being therefore evident that the' device possesses marked advantages over devices of this general character heretofore devised, since, although such devices employ structure similar to that described and claimed by me, they do not show the specific structure which I claim as my invention inner end of the hub and formed integrally therewith, and a movable'spoke clamping ring surrounding the outer end of said hub to slide endwise therefrom, the spokes being disposed between the two clamping rings;

of an annular retaining plate surrounding the axle and contacting with the inner end of the annular thrust member thereon, said plate also contacting with the fixed clamp ing ring, and a seriesof bolts passing removably through said retaining plate, through t e fixed and movable clamping rings, and through the intervening spokes, whereby the retaining plate, the bolts, and the movable clamping rings are the sole means to retain the entire hub on the axle and `for retaining the spokes on the hub.y

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses,
